I see the need to have an actual sedan in the lineup to replace the Intrepid but maybe they didn't need to call it a Charger.
Personally I'd rather they came out with a Challenger or Cuda rather than a Charger. The '05 Mustang is almost as big as the GTO...if Chrysler brought out an actual nice sized modern muscle car with the Hemi I think folks would throw down the cash. The LX cars have a 120 inch wheelbase which is freakin huge so a Challenger/Cuda would have to at the very least ride on a pretty well modified version of the platform.
